For the last two years I've carried a honeypot laptop with me every time I traveled. I checked it in my luggage, left it unattended in my hotel rooms. After each trip, I did forensic analysis on the laptop to detect if it had been tampered with.
@micahflee my infosec strategy: use a computer so idiosyncratic and jury-rigged that replacing parts, modifying the bootloader, etc., will probably result in the computer not working any more
@nev sounds like a solid, reliable strategy
